As an example of learning -- look at the first antenna on VK4YB's qrz
page. It's a brilliant design that isn't obvious -- when neighbor W6GJB
pointed me to it as one he wanted to build. I modeled it in NEC, looked
at the currents, and realized that what he had done was build something
that fit on his property that put a current maxima in the vertical
section at the middle of the antenna and without putting current maxima
where it could couple to lossy earth, which was what made the antenna
work. The rest was phasing and end loading.
Once I had understood the design, to fit it on Glen's real estate, I
simply split the long end loading into three parallel branches. He built
it, rigging the high parts from his redwoods, and had great success with
the antenna, working VK4YB, and many others.
